分析推土机用液力机械变矩器轴承支承结构的特点,根据液力机械变矩器叶轮轴向力的单向性特征,轴承支承结构型式布置成左边游动支承加右边单向固定支承的结构型式。SD8型的轴承支承结构右边采用单列圆锥滚子轴承,单列圆锥滚子轴承的轴向游隙在安装时,靠控制旋转总体右端面与限位调整隔环的间隙来调整,间隙小降低最高效率,间隙大减小轴承使用寿命,最佳间隙应该是液力机械变矩器的最高效率和单列圆锥滚子轴承的最长使用寿命这两要素最优组合的平衡点。最佳间隙不是装配出来的,而是磨合出来的。根据总装、出厂试验和性能试验的经验,总结出单列圆锥滚子轴承轴向游隙的调整方法。
According to the characteristics of hydrodynamic torque converter impellers bearing support structure, according to the unidirectional characteristics of hydrodynamic torque converter impeller axial force, the structure type of bearing support structure is arranged as the structure with the left swimming support and the right one-way fixed support Type. SD8-type bearing support structure on the right single-row tapered roller bearings, single-row tapered roller bearings axial clearance in the installation, by controlling the overall rotation of the right end face and limit the adjustment interval ring to adjust the gap to reduce the maximum efficiency , The gap greatly reduce bearing life, the best clearance should be the highest efficiency hydrodynamic torque converter and single row tapered roller bearing the longest service life of these two elements of the optimal combination of the balance point. The best gap is not assembled out, but run out of. According to the assembly, the factory test and the performance test experience, summarizes the single row tapered roller bearing axial clearance adjustment method.
